BACK-B A N D BUCKLE.

Patented Nov. 24, 1908.

Application led May 25, 1907. Serial No. 375,633.

To all whom it may concern:

Be it known that I, REUBEN C. ELDRIDGE, a subject of Great Britain, residing at Niagara Falls, Canada, have invented certain new and useful Improvements in Back-Band Buckles, of which the following is a full, clear, and exact description.

My invention relates to improvements in so-called back band buckles, the object being to provide a superior construction in which the webbing is more securely held than heretofore, the construction, as a whole, being economically produced without ysacrifice or waste of material.

In the drawings Figure 1 is a plan View of the buckle as closed, ready for use; Fig. 2 is a side elevation thereof; Fi 3 is a longitudinal section, the buckle icing open;

ig. 4 is a transverse section adjacent the plane of the bucklegripping member.

1 represents the frame of the buckle which is of suitable contour and which has the slots'2-3.

4 5 are ears struck up from the frame at oints near the opposite edges thereof and tween the passages 2 3.

6 is the clamping member pivoted at its ing member is out of action when standing, as shown in Fig. 3, and in action when stan ing, as shown in Figs. 1, 2 and 4. The lower edge of the clampmg member 6 is preferably serrated' as at 6, given a suitable turn, for example, the right angle turn shown in the drawings, so that when it is closed down, into its osition of use (as shown in Fi 2), it wil close the n il, which latter depends from the frame 1.

8 is a flange struck up from frame l in forming Vthe slot This flange is turned back upon itself so as to form an abutment or shoulder of double thickness against which the webbing, when attached to the buckle as in use, is forced by the clam )ing member Gf. Directly under llu` edge o the clamping member (3 are uynvarrlly struck nibs or projections 9 9. which preferably alternate wlth the aforesaid serrations, as best seen in Fig. 4. These nibs 9 9, the 1 while the free end is ser-rations 6, and the abutment 8, all coact 1n securing a eculiarly efective grip on the webbing and prevent slippage.

The nibs 9 9 may be economically produced by simply indenting the body 1 at its rear side so as to pro'ect or force the metal up on its opposite sur ace. By this arrangement all sharp teeth and points are avoided, which tend to cut oninjuriously abrade the webbing. The method of leading the webbing through the buckle is indicated in Fig. 3, in which it is shown as leading into the opening 2 from the rear, thence under the c amping member, thence through the opening 3 to the rear of the body 1.

Vhat I claim is 1. In a device of the character described, a buckle frame or body, ears struck up therefrom in the side of and near the edges thereof, said frame having two transverse passages or slots in the frame above and below said ears, the material of the body adiacent to one of said slots being folded back and down upon itself to form a raised shoulder on the upper face of said buckle frame, raised nibs on the same surface of said buckle frame struck u from the metal of said frame and closed.' adjacent to said shoulder, and a hingedI clamping member having a serrated edge, the serrations thereof arranged to alternate with said struck-up nibs.

2. In a device of the character described. a buckle frame or body, ears struck up therefrom at opposite sides thereof and near the edges, but spaced apart therefrom, a series of struck-up nibs in the body of the buckle in line with and between said ears, a raised rib parallel with and above said nibs and
